Purolite has been manufacturing resins for the food and beverage industry for over 30 years and has developed many products for related applications over this period. The food and beverage industry encompasses a wide range of resin applications including refining of sugar, sweeteners, collagen, dairy, ethanol, gelatin, glycerine, organic acids, amino acids, biomass, vitamins and fruit juices, among others. Purolite continually strives to develop better performing products for each industry guided by customer requirements. We actively seek customer feedback regarding potential improvements to current products that will help increase productivity and reduce operating cost.

Meeting Complex Regulatory Needs
Purolite’s food and beverage resins must meet FDA guidelines (USA) and REACH requirements (EU).
